Abstract (en)
[origin: WO0004498A1] In order to characterize video content, key frames are identified in that content. The key frames are collapsed into histograms. The histograms are grouped into families. The families are each represented by a family histogram. The family histograms characterize the video content. The family histograms can be used to determine program boundaries or index the video content.
